Languages & native names

Languages listed for Heard Island and McDonald Islands in the reference source, with native language names where available. This is not an exhaustive list of the languages spoken or a statement of their legal status.

No language entries are supplied in this source.

The small codes are source language tags. A tag such as en-US includes a language and a regional variant; it is different from an ISO country code on its own.

Heard Island and McDonald Islands time zones

IANA zone.tab does not supply a separate entry for this territory in the imported release. Time-zone identifiers describe clock-rule locations, not fixed UTC offsets.

UTC offsets and daylight-saving rules depend on the date and location. Use the time-zone converter to compare local times for a chosen date.
